I have a problem and I think i know the solution but I don’t want to waste any more on a new bit that may not work.
I have the porter cable 4210 jig and I am using the 1/2 box joint jig i bought for it.
This creates a space about .018 to .020
So I figured since 1/64 is .015 changing the bit to a 31/64 would get me within .003 and .005 over and they would be tight
So I think because I am not a CNC machine, or lack of years of practice and since I don’t have unlimited board feet to practice with; maybe compensate for that with a undersized bit, like the 31/64th (undersized 1/2).
I normally make my boxes out of walnut, pine, oak or maple .
Do you guys think that would work or would they be too tight and I would end up having to sand the crap out of them to fit. My thinking is tighter is better because then I could always remove a little but I don’t want to be there all day on a joint…would the wood compress and give me the space I need or do you think I would be asking too much from a hardwood..
Am I overlooking something? I don’t like wasting money so I figured I would run it by all your brains.
